Seeking to bolster the quarterback position following a potential season-ending knee injury to backup Luke McCown, the Buccaneers on Thursday signed unrestricted free agent Jay Fiedler, who had visited last week with team officials, to a one-year contract. Although he is still rehabilitating from December shoulder surgery and may not be able to throw at full velocity until training camp late next month, the Bucs are confident that Fiedler can contribute this year for them, especially if starter Chris Simms is injured.
